Outpatient subcutaneous alemtuzumab is feasible and safe for aplastic anemia and is associated with high response rates

Immunosuppressive therapy Immunosuppressive therapy: Immunosuppressive drug therapy lowers your body's immune response. This prevents your immune system from attacking your bone marrow, allowing bone marrow stem cells to grow, which raises blood counts. For older patients with acquired aplastic anemia, immunosuppressive drug therapy is the… using horse antithymocyte globulin antithymocyte globulin: ATG is an immunosuppressant, a drug that lowers the body's immune response. It is typically used with cyclosporine as the first-line immunosuppressive therapy (IS) to treat patients with acquired aplastic anemia. In some cases it is used as a treatment for patients with MDS and PNH. (ATG; h-ATG) combined with cyclosporine cyclosporine: Cyclosporine is used along with antithymocyte globulin (ATG), another immunosuppressant, for treating aplastic anemia and some other forms of bone marrow failure. (CsA) and eltrombopag eltrombopag: What are the possible side effects of eltrombopag (Promacta)? Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat. Stop using eltrombopag and call your doctor at once if you have: … is the standard care for aplastic anemia aplastic anemia: (ay-PLASS-tik uh-NEE_mee-uh) A rare and serious condition in which the bone marrow fails to make enough blood cells - red blood cells, white blood cells, and platelets. The term aplastic is a Greek word meaning not to form. Anemia is a condition that happens when red blood cell count is low. Most… (AA) in patients without a suitable matched donor. However, in many countries, h-ATG use has been discontinued, leaving rabbit ATG (r-ATG), which has a lower response rates and poorer survival, as the only alternative. In previous studies, alemtuzumab alemtuzumab: Alemtuzumab is a drug used in the treatment of chronic lymphocytic leukemia (CLL), cutaneous T-cell lymphoma (CTCL) and T-cell lymphoma under the trade names Campath, MabCampath and Campath-1H, and in the treatment of multiple sclerosis as Lemtrada. It is also used in some conditioning regimens for… (ALZ), a humanized monoclonal antibody monoclonal antibody: A type of protein called an antibody that is engineered to look for a specific substance in the body. There are many kinds of monocloncal antibodies. Each one looks for only one substance. Eculizumab (Soliris) is an monoclonal antibody that may be prescribed to treat patients with paroxysmal… targeting CD52, combined with CsA, resulted in an adequate overall response rate (ORR) in patients with AA. This study describes a multicenter, international retrospective analysis of ALZ for treating AA.We analyzed a series of patients who received subcutaneous ALZ for AA in 4 centers in Brazil and the United Kingdom from March 2009 to January 2024. We analyzed 64 ALZ treatments in 61 adult patients with AA, 76% with severe AA (SAA) or very SAA. The ORR was 59.4% at 12 months (complete, 21.9%; partial, 37.5%). Cumulative incidence (CI) of response was 54.7% at 6 months and 59.4% at 12 months. Younger patients (age <65 years) had higher CI of response (67% vs 31%; P = .03), as did patients treated with a total dose of 103 mg (70% vs 38%; P = .02). Overall survival was 86% at 1 year, 78% at 2 years, and 70% at 4 years, significantly higher in responders (90% vs 44%; P < .0001). Adverse events were of low grade, and infectious events were infrequent. Subcutaneous ALZ is a feasible, effective, and safe alternative to r-ATG for patients with AA requiring immunosuppressive treatment when h-ATG access is limited.
